DEIF DVC 550 — Digital AVR (Automatic Voltage Regulator)
DVC 550 — high-performance digital AVR platform
Digital voltage regulators (AVR) for synchronous alternators with PID tuning, multi-mode operation (AVR/PF/kVAr/cross-current), grid-code functions and remote configuration.
Overview
The DEIF DVC 550 is a high-performance digital AVR (automatic voltage regulator) for synchronous alternators. It replaces legacy analogue AVRs with full digital control, PID tuning, multi-mode operation (AVR/PF/kVAr/cross-current) and grid-code functions. S.A.International supplies the DVC 550, DVC 310 and DVC 100 digital AVRs across Tamil Nadu.

Frequently asked questions
What does a digital AVR (DVC 550) do?
An automatic voltage regulator maintains an alternator's output voltage by controlling field excitation. The digital DVC 550 adds PID tuning, power-factor/kVAr modes, cross-current compensation, protection and diagnostics, and remote configuration.
